RCA JAN 6SN7GT VT231 Gray Glass Well Balanced (4.9%) Single NOS 6SN7 VT-231

This is a well balanced single RCA JAN 6SN7GT VT231 vacuum tubes. It was manufactured in the USA by RCA for the US military. It has a medium glass envelope and a thick, black base. Both plates test very close to each other. It was manufactured to rigorous military specifications, so you can expect low noise and microphonics. This tube haas staggered black plates, white lettering, and a bottom getter. These are highly sought after RCA JAN 6SN7GT tubes, act quickly before they sell out!! More available upon request.

**There is a slight rattle from a loose piece of non-conductive glass inside the tube. This will not affect the tone of the tube***

Be careful buying tubes from sellers who list tubes as matched if they do not provide test results or the equipment that they tested their tubes on.

I personally tested these tubes on my recently calibrated Hickok 600a and my TV7D/U and the results are as follows:

3,050/2,900
